GRAIN-SEPARATOR.

SPECIFICATION forming part of'Letters Patent No. 269,000, dated December 12, 1882.

\ Application tiled MayQO, 1882. (No model.)

. exact description of the construction and operation ot' the same,"`reference being had to the annexed drawings, making a part of this speciication, and to the letters and figures of reference marked thereon. i

Figure l of the drawings is a vertical sectional view of my separator. Fig. 2 is a rear view of the same with the fan-casing and fan removed,and Fig. 3 is a detail perspective view of one of the arms of the fan.

This invention has relation to grain-separators; and it consists in the construction and arrangementof parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, the letterA designates the uprights of the case; B, the side walls, which are of tapering form, being' wider toward the frontend, where the fan-case l) is located.

C indicates -the sloping top, which shelves downward and backward to the open end E, where the chaff is blown out.

F represents the bottom guide-board, which shelves downward from the open end E, eX- tending to the edge of the rst transverse discharging-chute G, into which it delivers.4

H represents the long shoe, which extends from under the hopper K to the open end E ot the case, andis suspended to the upper portion thereof by staples and links. It is provided under the hopper with the inclined guideboard L, the slope of which is like that of the top O of the case. the inner end a of the upper or first coarse screen, S, the slope of which is slightly inward, or from the open end a of the screen forward, as indicated in the drawings. Under the screen S, and parallel thereto, is the second coarse screen, S', the inner end a ot' which is situated immediately under the inner end` a of the upper screen. 'lhe bottom or line screen, S", has a much steeper, inclination or down- This board deli-vers upon.

ward slope from the open end of the case fori ward to its delivery end a, which is situated immediately over the separating partition or walls b, between the transverse delivery-chutes G and G. The tine screen S extends a little in front of the upper coarse screens, and receives what passes' over the ends thereof, in this manner conveying the larger grain into the second chute, G'. The tine seed and cockle pass through the screens, and are conveyed' by theinclined bottom guide, F, into thersttransverse chute, G, which lies under the inner end The transverse tion ofthe case, so that theblast will meet it,

whereby an excellent cleaning effect is produced. The dividing wall or walls b between the chutes'is arranged immediately and verltically below and near the inner end a of the `line scree'n, the slope of which is sut'iiciently rapid to prevent clogging, and to allow time for the blast to take eli-'ect upon the chaff and light stuft which passes through the upper screens. The tapering blast-throat V, between .the sloping top O and the inclined bottom guide, F, is designed to produce, when the fan is in operation, a concentration of tlhc wind, so that the light statt will be blown out in a forcible manner.

The fan-shaft c is rectangulaig-and -is formed with cranks g at the sides within the case, which are connected to the sides ot the shoe by the horizontal pitman-rods It. rlhe sbatte is made round where the pitman-cranks surround it, and is provided with a pinion, fk, which engages the driving-wheel Z.

P represents the fan, which consists of four blades, R, connected by arms m. These arms are formed withV lateral notches a, whereby they engage each other, and with smaller rectangular notches, e, for the reception of the fanshaft e, made in the opposite edges from the ICO fan-blades, and having their bottoms at right angles, so that when they are adjusted on the squared shaft e and the sections are moved together by a sidewise motion they will be 5 lockedon theshaft. Fastening-pinstareplaced in perforations through the shaft to secure the sections in position after adjustment.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. 1n a grain-*separator having the downwardly-inclined top C and the oppositely-inclined bottom guide, F, the combination therewith of the shoe H, having the downwardly- 15 inclined guide-board L, extendingr to the lower end of the screen S, the screens S, S', and S, and the transverse inclined discharge-chutes G G', substantially as specied.

2. In a grain-separator, thecoinbination of the rectangular fan-shaft e, having lateral zo cranks g, pitmen h, fan-blades R, notched interlocking arms m n z, engaging eachother, and the fan-shaft, substantially as specified.

In testimony that I claim the ahov'l have hereunto subscribed my'narne in the presence 25 of two witnesses.

y JOHN BRUNNER.
